# Is a clone the same sex and age as its mother?

> A cannabis clone is genetically the same as its mother, including her sex: every clone of a female is female. It is also physiologically mature, not a new seedling, so it can flower as soon as it gets 12/12. Apart from rare somatic mutations and carried-over pathogens such as hop latent viroid, it is the same genotype; there is zero genetic drift.

## Short answer

A cannabis clone is the same [genotype](https://genetixbay.com/knowledge/glossary/genotype.md) as its mother, so it is the same sex: clones of a female are female. It is also mature tissue, the "age" of the mother rather than a [seedling](https://genetixbay.com/knowledge/glossary/seedling.md), and can flower as soon as it gets [12/12](https://genetixbay.com/knowledge/glossary/12-12.md). *Established*.

## Why

[Cloning](https://genetixbay.com/knowledge/glossary/cloning.md) is vegetative propagation: a rooted cutting carries the donor's full genome, including the [sex chromosomes](https://genetixbay.com/knowledge/glossary/xy-sex-determination.md) [1].

Mutations are rare and not a loss. Sequencing finds a few somatic mutations accumulating in different parts of a plant and its clones [2]. House position: zero [genetic drift](https://genetixbay.com/knowledge/glossary/genetic-drift.md) in a well-kept cut apart from pathogens.

Cuttings keep their physiological age. Propagation science calls this cyclophysis and [topophysis](https://genetixbay.com/knowledge/glossary/topophysis.md): a cutting carries the maturity and character of the shoot it came from [3]. That's why a clone can flower small and why cuts from different branches can behave differently for a while.

Pathogens travel too. [Hop latent viroid](https://genetixbay.com/knowledge/glossary/hop-latent-viroid.md) passes through infected cuttings and reduces flower mass and quality, often without obvious symptoms [4].

## The numbers

| Trait | Same as mother? |
|---|---|
| Genotype | Yes, apart from rare somatic mutations |
| Sex | Yes |
| Ability to flower | Immediately on long nights ([photoperiod](https://genetixbay.com/knowledge/glossary/photoperiod.md)) |
| [Chemotype](https://genetixbay.com/knowledge/glossary/chemotype.md) potential | Yes, environment permitting |
| Pathogens (HLVd, [mites](https://genetixbay.com/knowledge/glossary/two-spotted-spider-mite.md)) | Yes, if present |
| Early growth habit | Can differ by cutting position |

## What to do

1. Take cuts from consistent locations: vigorous upper-to-mid shoots.
2. Label every clone with its source and date.
3. Test valuable [mothers](https://genetixbay.com/knowledge/glossary/mother-plant.md) for HLVd and quarantine new cuts.
4. Expect a clone to flower small; give it enough veg for the canopy you want.
5. Compare clones side by side before blaming "genetics".

## Common mistakes

- Expecting a clone to need weeks of "growing up" before it can flower.
- Assuming a clone of a [herm-prone](https://genetixbay.com/knowledge/glossary/herm-prone.md) plant will be stable.
- Blaming age for a weak cut without testing for HLVd.
- Taking cuts from random spots, then calling them different [phenotypes](https://genetixbay.com/knowledge/glossary/phenotype.md).

## Follow-up questions

**Why do clones from the same mother grow differently?** Clones from the same cannabis mother can grow differently because of position effects, called topophysis: a cutting can 'remember' whether it came from a vigorous leader or a shaded lower branch. This is a physiological carry-over and may or may not involve mutation. Pathogens such as HLVd, and differences in how cuts are rooted and grown, also cause differences.

**Can a clone flower straight away?** Yes. A rooted cannabis clone from a photoperiod mother is mature tissue, so it can flower as soon as it gets long nights, even at 15 cm (6 in) tall. That is how sea-of-green growers flower small clones after a short veg. A clone from an autoflower is a different case: it keeps the mother's countdown and usually flowers small.

**Do clones get weaker with every generation?** No. GenetixBay's position is that a well-kept cannabis cut shows zero genetic drift apart from pathogens such as hop latent viroid. Sequencing does find rare somatic mutations, but no study links them to the decline growers describe, and the founder keeps cuts over 40 years old with no decline. If a cut 'got weak', test it for HLVd first.
